HEATING STOVE.

Application filed June 14,

This invention relates to heating stoves, and has for its prln'iary object to provide a, highly novel and simply constructed stove that will radiate great heat and that will. not require frequent replenishing of the fuel as the nature of the stove is such as to receive a large fuel supply that will automatically feed to the fire grate when the burned coals are discharged therefrom.

Other objects will become apparentas the nature of the invention is better uiule-rstood, the same comprising the novel forms, com-- bination, and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing Figure 1 is a side elevation of a stove constructed in accordance with the present invention, parts being broken away to more clearly illustrate the vertically movable grate and the actuating means therefor.

Figure 2 is a detail vertical transverse section of the stove, and V Figure 3 is a 't'ragl'nentary longitudinal section of a slightly modified form of stove constructed in accordance with the present invention whereby the same may be employed in the heating of water.

First having reference to Figures 1 and 2, my novel stove constitutes the provision of a pair of circular drums 5 and 6 of different diameters ar anged one Within the other in concentric relation as clearly disclosed in Figure 2. The inner drum is of corrugated sheet metal and is of gradually increasing thickness toward its bottom side as clearly disclosed in Figure 2. The outer drum 5 is formed with end walls 77 that are formed with circular openings for receiving the ends of the inner drum 6 after which said ends of the drums are welded within the openings of the end walls of said outer drum 5.

At the bottom side of the outer drum 5 the same is formed throughout its entire length with a fire box 8 that is equipped with a desirable form of draft inlet 9, and a cleanout door 10. This fire box 8 communicates with the space intermediate the drums 5 and 6 and slidably arranged therein is a horizontal tire grate 11 of arcuate formation in the direction of its width in order to correspond to the curvature of the outer drum 5 when said grate is in position at the upper end of the the box shown in both Figures 1 and 2,

1926. Serial No. 116,054.

this grate being suitably slidably mounted upon guide rails 12 disposed upon the op posite side walls of the tire box at the upper end thereof to facilitate the vertical sliding movement of said grate.

Depending from the grate 11 are two or.

that the same may be rotated in opposite directions for facilitating the raising or lowering of the grate as desired.

The top wall of the outer drum 5 is formed with u. flue 1.7 for attachmentto a smoke dis charge pipe the front wall of said line being formed with a fuel'receiving opening 18 that is normally closed by a hinged door 19.

in use, the grate 11 is lowered within the lire box to permit the lire to gain headway after which the same is raised to the position disclosed for bringing the hot coals directly within the space between the drums 5 and ti and in contact with the inner drum for heating the same which will result in the radiation of great heat. The entire area of the space between the drums may be charged with fuel in order that the same will auton'latically feed to the grate asthe burned coals drop therefrom by gravity or through the shaking of the grate which may be accon'iplished by rapidly raising and lowermg the same.

In the form of the invention disclosed in Figure 3 the stove consists also of inner and outer spaced concentric drums 5 and (3, but in this instance the end walls 7 of the outer drum 5 are not formed with openings but serve as closures for the opposite ends of the inner drum so that water may be projected therein to be heated. In this instance it is of course to be understood that means must be provided to facilitate the inlet of cold water and the exhaust of the hotwater to and from said inner drum as suggested in the figure.

It will thus be seen that I have provided a highly novel, simple and efficient form of stove that is well adapted for all the purposes heretofore designated and even though I have herein shown and described the most preferred embodiments of the present invention it is nevertheless to be understood that other modifications may be had without effecting the spiritnnd scope of the appended claims.

Having thus described the invention, what I claim as new and desire to sccureby Letters Patent is:-

1. ln :1 Store 01 the class described,n pair oi horizontully arranged spaced concentric drulnaa, providing Ztfuel receiving chamber uround the innerdruin, a tire box on the bottom of the outer drum in con'nnunicntion with the fuel chzn'nbel', a grate arranged in the tire box, a fine extending" from the top of the outer drun'iundcommunicating with the fuel chamber, said flue providing an inlet for the delivery of the fuel to said chzunbenthe fuel being delivered to the grute 'by gravity.

2. 1n nstove of the clues described, :1

pair of horizontally nrrangedspaced con centric drums, the inner drum being corrugated and gradually increasing in thickness toward its bottom, said drums forming a substantially circular fuel receiving ehemher around the inner drum, the bottom of the outer drum having an opening formed therein for its entire length, n lire box arranged below the opening, a grate disposed in said opening and being curved to conform to the contour of the outer drinn, n flue extending upwardly from the top of the outer druni and communicating with the fuel ceiving chamber, said line having an opening formed in theeide thereolbto pern'iit fuel to be delivered to the fuel chamber, end :1 closure for the opening, the fuel in the chamber beingriled to the grateby gravity.

In testimony whereof I nflix niy signature.
